1 Claim. (Cl. 282-28) This invention relates to new and usefulimprovements in carbon paper for making carbon copies.

More particularly, the present invention proposes the construction of animproved carbon paper guide which will permit the user to tell quicklyand conveniently when the carbon paper is correctly in place and whichwill permit pages of approximate lixed numbers of words to be easily andmechanically produced with uniform margin and symmetry.

As a further object, the present invention proposes forming the carbonpaper guide of a sheet of carbon paper marked, perforated or cut withvertical and horizontal indications to show the user where to begin andwhere to end a 30D-word page with a one inch margin or a 250- Word pagewith a one and one-half inch margin.

Still further, the present invention proposes constructing the carbonpaper guide with the Vertical and horizontal indications located indiagonally opposed corner portions in sets so that the life of thecarbon paper sheet may be extended by turning the sheet around.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claim in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a front perspective view of a carbon paper sheet constructedand arranged in accordance with the present invention, when the carbonpaper is of the exact size of the writing paper.

Fig. 2 is a rear perspective view of the sheet shown in Fig. l.

Fig. 3 is a sectional view taken on line 3--3 of Fig. 1.

Fig. 4 is a sectional View taken online 4-4 of Fig. l.

Fig. 5 is a View similar to Fig. 1 but illustrating a modification ofthe present invention.

Fig. 6 is a fragmentary perspective View of the structure shown in Fig.5.

Fig. 7 is a view similar to Fig. 5 but showing both sets of additionaldiagonal guide indications removed.

Fig. 8 is a view similar to Fig. 2 but illustrating another modiiicationof the present invention.

Fig. 9 is a view similar to Fig. 1 but illustrating a still furthermodification of the present invention.

The carbon paper guide, in accordance with the first form of theinvention illustrated in Figs. 1 to 4, inclusive, comprises a sheet ofcarbon paper 15 of the same size as standard typewriter paper of thetype commonly used in typing manuscripts, letters and the like.

Sheet l5 has the usual carbon face 16 and plain back 17 and preferablyis of the same thickness as the usual sheet of carbon paper and can bemade from the same.

Sheet 15 has like diagonally opposed upper left and lower right cornerportions 1S and 19, respectively, and like opposed upper right and lowerleft corner portions 20 and 21, respectively.

Corner portions 18 and 19 have like spaced vertical margin indications22 and 23 and like spaced horizontal starting and finishing indications24 and 2S. Indications 22 and 24 are formed on the sheet by cutting orotherwise forming cut-out portions on sheet 15, indications 22 and 24being edge portions of the sheet. The indications 23 and 25 spacedparallel to indications 22 and 24, respectively, are lines formed uponthe back 17 of the sheet 15.

In the example shown in Figs. 1, 2, 3 and 4, the indications 22 and 24are formed by cutting a one inch square from the upper left and lowerright corners of the sheet 15. The indications 23 and 25 are linesformed by a one and one-half inch square formed preferably beforeindications 22 and 24 are cut.

Sheet 15, in addition, has in diagonally opposed upper right and lowerleft corner portions 20 and 21 spaced vertical margin indications 26 and27 and horizontal starting and finishing indications 28. The indications26 and 28 are formed by cutting out a corner of the sheet, theindications 26 and a portion of indications 28 being edge portions ofthe sheet. Indications 27 and a portion of indications 2S are linesdrawn on the back of the sheet. In the example shown in the first fourfigures, the indcations 26 and part of indications 28 are formed bycutting a one-half inch by one inch rectangle from the sheet corners andscribing a one-half by one and one-half inch rectangle in the samecorners of the sheet. The vertical indications 26 and 27 serve as guidesfor 'the vertical margins of typing matter and the indications 28 serveto indicate the starting and finishing points of typing matter on thesheet being typed.

The new carbon paper guide in the example shown is based on the standardsix lines to the vertical inch on all makes` of typewriters and may beused primarily to guide those who transcribe manuscripts for submissionto editors. The diiierence in the cut-out corner portions serves toprevent the carbon paper sheet from being improperly positioned, i. e.for the reverse or carbon side to be transposed. The guide indicationsassure perfect uniformity and symmetry.

instructions for using the carbon paper guide are as follows: Do not useopaque paper. Adjust sheet with carbon paper in the usual manner. Thenadjust the rear and front sheets to the one inch or the one and one-halfinch indication. The larger cut-out should be visible in the upperleft-hand corner of the sheet to prevent using the wrong side of thecarbon paper. If a 30G-word page with a one inch margin is desired, usecarbon paper cutout corner edge portions as guides. If a 250-Word pagewith one and one-half inch margin is desired, use the scribed or drawnlines as guides. Writing starts at the intersection of the horizontaland vertical cut-out portions or scribed or drawn lines. The last lineof a page is written when the horizontal side of cut-out or scribed ordrawn lines shows in the lower right-hand corner. To increase the lifeof a sheet of carbon paper, one should alternate starting with the upperleft and lower right cutouts or scribed or drawn indications.

The modification of the invention illustrated in Figs. 5, 6 and 7 ischaracterized by a carbon paper guide sheet 39 constructed similarly tosheet 15 and having similar parts given the same reference numerals butprimed to distinguish the figures. In Figs. 5 and 6, on sheet 39,however, the alternate sets of vertical margin indications andhorizontal starting and finishing indications instead of being drawn orscribed on the sheet, are perforated lines. In the use of sheet 30,therefore, the user may tear the sheet along the perforations to obtaina Z50-word page guide. This will form a larger cut-out corner portionwith edge guide indications which may be more easily n 2,792,239 l lseen through the paper being typed upon than the drawn or scribed lines.

In Fig. 7, the alternate sets of vertical margin indications andhorizontal starting and finishing indications are omitted. Y

The modification of the invention illustrated in Fig. 8 is characterizedby the provision of a carbon paper guide consisting of a sheet of carbonpaper 31 with square corners which are clear or ytranslucent anduncarboned. Sheet 31 Vhas the usual carbon backing 32 on all the otherparts of the sheet except the corners.

Upper right and lower left corner portions 33 and 34, respectively, havevertical margin indications 35 and horizontal starting and nishingindications 36 which are the carbon edge portions of the clear ortranslucent corner portions 33 and 34. In the example shown, cornerportions 33 and 34 are one inch square.

Upper left and lower right corner portions 37 and 38, respectively, havevertical margin indications 39 and horizontal starting and nishingindications 40 which also are the carbon edge portions of these clear ortranslucent corner portions. In the example shown, the corner portions37 and 38 are one-half inch by one inch rectangles.

The modification of the invention illustrated in Fig. 9 is characterizedby the provision of a sheet 45 of carbon paper which is longer than thestandard sheet of type- Writer paper. This carbon paper has clippedupper left and lower right corners 46 and 47, respectively. In addition,scribed, marked or perforated on the back 48 of sheet 45 adjacent theclipped corners 46 and 47 are vertical margin indications or lines 49and 50 and a like alternate set of indications or lines 51 and 52.Connected with the vertical margin indications or guide lines 49 and 50are horizontal starting indications or guide lines 53 and 54. Analternate set of horizontal starting indications or guide lines 55 and56 are connected with the alternate set of verticalV margin indicationsor guide lines 51 and 52.

The upper right-hand corner portion 57 and lower left- 4 hand cornerportion 58 of sheet 45 is marked, scribed or perforated with venticalmargin indications or guide lines 59 and 60 and with horizontal inishingindications of guide lines 61.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to |theprecise constructions herein disclosed and that various changes andmodifications may be made within the scope of the invention as definedin the appended claim.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent is:

A carbon paper guide for typing carbon copies, comprising a rectangularsheet of carbon paper having side and end edges disposed perpendicularto each other, said sheet having a rectangular cut-out at each of thefour corners thereof, each of said cut-outs having a vertical sideperpendicular to one end edge of the sheet and a horizontal sideperpendicular to the adjacent side edge of the sheet, said vertical sidedefining a vertical typing margin indication, said horizontal sidedefining a horizontal typing margin indication, rthe length of thevertical side being equal to the width of the horizontal typing margin,the length of the horizontal side being equal to the width of thevertical typing margin, the side and end edges of the sheet beingstraight along the entire perimeter of the sheet between the cut-outs,said sheet having two right-angled perforated lines disposed adjacent toeach of said cut-outs for enlarging said cut-out to a predeterminedsize, the two perforated lines being respectively parallel to the twosides of the adjacent cut-out, said two perforated lines respectivelydefining other vertical and horizontal typing margin indications.
